IMPROVEMENT IN CHAIR-CLAMPS FQR RAILWAY-RAILS.

, The Schedule referred to nthese Letters Patent and making part of the same.

To all whomI 'it may concern: g Be it' known that I, WILLIAM Monnuonsn, o Buffalo, in the/ county ot' Erie and State oi' New York, have invented a new and improved Bailroadf Rail Clamp and I do hereby declare that the i'ollowing is a full, clear, und exact description thereof', reference being had to the accompanying drawing making part of this specification, in which- .Y Figure 1, plate l, isY an elevation of one side of a rail-joint, showing thevchairs applied to the same.

Figure 2, plate 1, is a top view oi' the joint. Figure 3, plate?, is a cross-section of the joint. Figure 4, plate 2, shows a modification of the chairclamp. v

1 Figure 5, plate 2, is a perspective view oi' the chairclamp of figs. l, 2, and 3. 1 vSimilar letters of reference indicate correspondingr parts in theseveral figures. j

This invention relates to jan' improvement which is designed foriirnily clamping, v support-ing, and holding down railroad-rails at their joints, where fish-bars or splicing-bars arc employed between the heads and bases-oi' the rails. l

Theobjcct is to render unnecessary thc punching of' the fish-bars and the websot the rails, which is not only expensive, but which weakens the rails at those points where they should be the strongest.

The nature of my invention consists` First, in a combined chair and clamp,rso constructed that, in the act- .of coniining it'to the cross-ties or to' blocks between the cross-ties, its jaws will rml y clamp and hold the fish-bars in piace on opposite sides of the rail, as .will be hereinafter explained.

Y Second, in adapting` the fish-bars to receive and be heldin place by thefcnds ofI thc improved clampingchairS, as 'will be hereinafter explained. The following is a description ot' my invention:

In the accompanying drawing- A. A represent the ends of the two rail-sections oi' the well-known T-shapc; and

B B represent two ish-bars, which are used on opposite sides of the webs oi the sections for splicing the sections and supporting the lips thereof at the. jolnt,

and, if desirable, at intermediate points between the j ends ofthe rails. 'lhcse ishbars are preferably lmade i* concave-conver,v as shown in the sectional views,` figs.

3 and 4, although they may be made of a different shape.

' Each bar B is constructed with depressions b, in its outer side, adapted to receive the ends of the clamping-chairs. As the equivalent 'of these depressions lugs may be formed in any suitable manner on the surfaces of the bars.

The combined chair and clamp C is so constructed that it aiiords a base portion, c?, and two side-griping jaws, terminating upwardly 'in lips which are received into the depression b in the [ish-bars B B.

By reference-to figs. l, 2, and 3, it will be seenthat 4the jaws of the clamp are bent at obtuscangles, and

that the portions c c are punched to receive-through them the bolts, spikes, or screws which confino the clamp down iii-.place upon the cross-ties, or upon on the extremities of the base-piece prevent the jawpieces from spreading ont when the to a rail.

Having described my invention, Vhat I claim ,as new is- `1. The chair and clamp, consisting of a base, 02, jaws U C, and bolts l) or D', substantially as and for the purpose described.

2. The combination of the recessed fish-bars B l1, chair and clamp C C c2, and bolts D or D', substanparts are clam pcd tial] y as described.
